I, .SAMUEL WALSH, of New York, iii the county and State of New York,have invented certain Improvements in Sinks, of which tlic following isa specincation.

My invention embraces such improvements in the manufacture of cast-ironsinks and traps, by means whereof the cost of manufacture is greatlyreduced, and enables persons who are not mechanics to clean out the trapwhe'n stopped up, thus saving the trouble and expense of calling in aplumber for that purpose, as has now to bc donc with the sinks and tmps:it present in use. I

The sinks and traps as now made are cust separately, and arc fastenedtogether by two or moi'e bolts. I

The traps are known as the S-traps, and often lwhen stopped up have tobe separated t'rom the sink to be cleaned out; they are not alwaysperfect traps, for if a large body of water is poured iiit-o the sink,or is passing down the main pipe, with which the several pipes from thesinks of a tenement-house connect, the S'is liable to actas a Siphon anddraw'out all the water froni the trap; when, of course, it does notanswer the purpose for which it was designed, but allows the cttluviafrom the drain to pass into the building.

Iobviatc all these difficulties by iny invention in making the sink andtrap in one casting, and by using an improved forni of trap.

lnilie accompanying. drawing forming part of this specification- 'Figure1 is a section of my improved sink;

Figure 2 is a plan of the same, with the strainer i-inoved; and

Figure 3 is a view of the under side of the strainer. The sink It iscast with the body of the Atrap b, in the center of which is the shortpipe c, standing up a short distance from the bottoni of the trap b, andextending below asiitiicient distance to make the connection with thewaste-pipe.

Near' the top of the trap b is the inside tiange 1i', upon which thestrainer' d rests. f

On the under side of the strainer rl is the inverted cup ll, which, whenthe strainer is in place, extends below the top of and outside the pipec, but does not touch it, leaving a sufficient space for a' freeVpassage of Water.

The strainer'd is provided with the lips d2 d?, which pass throughbreaks in the flange b', and thestramer being turned partly round, theycatch under the angc Vcast two inclined tia'nges, c c', which hold thecoupf ling e, by means of two projections, e' e', on the inside of thecoupling.

The end of the' waste-pipe, which is made of lead', is passed throughthe coupling e, and spread out so as to tit the inside. of it; thecoupling is then placed over the end of the pipe c, with the projectionse e', bearing on th'e inclined a'nges c c', and turned round until thelead pipe is pressed sntciently between the coupling@ and end of thepipe c to make a tight joint.

Some putty may be applied 'to the joint, if found necessary.

Instead of the inclined tlauges, two lugs may be cast on the pipe c, forbolts to pass through them, and corresponding lugs on the coupling, asis now in general use.

When the trapjs stopped up, the strainer d is removed by .turning itroiiud until the lipsd2 ol2 are opposite the breaks in the ange b'; itisthen lifted outand the trap very easily cleaned.

1f the stoppage is in the waste-pipe, a wire or stick may be used toremove it, .or the water-,hose may be fitted over the pipe c, and thepressure of the water from the hydrant is often suicientto removeobstructionsin the waste-pipe.

I claim as my improvement in sinks- A sink,`cast `with the trap, in one.piece, in the manner shown and described.

SAMUEL WALSH.
